Hannah Stone, 27 is said to be dating the 48-year-old Welsh bass-baritone opera singer after the pair became close when performing together and she featured in a TV special hosted by Mr Terfel last Christmas.

Friends told The Mail on Sunday that the pair are currently on holiday in Spain and are "very happy", while planning a future together.

The relationship became known in classical musical circles when the couple were spotted attending each other's concerts.

Last month Mr Terfel was seen watching Ms Stone perform at the Fishguard Musical Festival in South Wales.

A fan Trevor McCrory tweeted a photograph of him loading up her harp in to a car after the concert, while another photograph showed the couple saying farewell to a group of friends.

Fishguard Festival manager Geraint Hodges said: "It’s not any great secret in music circles that they are a couple."

Just a few days before she appeared alongside Mr Terfel in a Christmas special, he tweeted a picture of Ms Stone gazing in to her dressing room mirror writing: "Hannah Stone, our beautiful royal harpist, getting reading for her solo."

The Prince of Wales' official harpist is understood to have split from her husband of two years and Welsh singer, Gary Griffiths. He is reported to have left the martial home, a luxury flat in Cardiff bay, but has made no mention of the split.
